MOTOR ROLLER-SKATE.

Specification of Letters Patent.

Patented June 12, 1906;

Application filed October 2,1905. Serial No. 281,040.

u .To aZZ whom it may concern,.-

Be it known that I, HENRY BEAUFORD, a

I, citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Motor Roller-Skates;

durable in construction and convenient and .n eiclent 1n operation.

With the above and other objects in view Athe invention consists of certain novel fea-Y tures of construction, combination, and ary rangement of parts as will be hereinafter de-- f Y scri ed and claime In the accompanying drawings, Figure 1 is al side elevation of one of my improved automobile skates. Fig. 2 is a similar view ofthe opposite side of the same. Fig. 3 is an end e evation, and Fig. 4 is a vertical transverse sectional view.

The embodiment of my invention shown in the accompanying drawings com rises a body 1, which is adapted to be securedp to a persons foot and which is mounted upon supportingwheels 2, which are geared to a motor 3, carried by said body. The body 1 and its supporting-Wheels 2 are preferably constructed similar to the bicycle or cycle skates now in vOeneral use; but they may be of any other iorm and construction from that shown. The body 1 comprises a base-plate 4, which has an extende rear portion 5 and de ending brackets or hangers 6 upon its undler side. The base 4 is shaped to fit a shoe and is secured thereto by the usual stra s 7, the heel of the shoe resting in the usua heel ortion 8 of the skate. The supporting an drive wheels 2, 0i which two are preferably provided, one being at the front and one at the rear, are suitably journaled in bearings in the brackets or hangers 6, and they are preferably provided With rubber rims or tires, as shown.

The motor 3, which is here shown in the form of an explosive or gasolene motor, is

, suitably secured, as shown at 9, upon the extended portion 5 of the base 4 and it may be of any4 suitable construction. As shown, its

`suitable contro lmg operati parts are disposed in a-casing 11, through earings in which extends a powershaft 12. On one end of the shaft 12 is secured a bevel-gear 13, which meshes with a bevel-pinion 14, secured upon one end of a shaft 15, which is journaled in bearings 16, provided upon the casing 11 and the rear anger 6. On the opposite end of said shaft is secured a bevel-gear 17, which meshes with,

a similar gear 18, secured upon one end of the shaft 19 of the rear wheel 2.

ar bevel-gear 20, which mes brackets 23, as clearly shown in Fig. 2 of the drawings. site endD a bevel-pinion 24which meshes with a bevel-.gear 25, secured upon one end of the shaft 26 of the front wheel or roller 2. It'

will be seen that when the power-shaft 12 of the motor is in operation its motion will be imparted, through the gearing just described, to the two whee s 2,' so as to rotate the latter and propel the skate.

previously stated, the gasolene-motor 3 may be of any well-known or preferred construction, and, as shown, has supported from its casing a carbureter 27, to which oil and air are supplied through suitable pipes 28 29. The oil-supply pipe 28 contains a suitable controlling-valve 30, which is here shown in the form of an angle-cock and leads from a gasolene tank or container 31, which is sup ported beneath the base 4 of the skate in rear of the front wheel 2 upon a suitable frame 32, which connects the front and rear han ers or brackets 6. The lever 33 on the coc or valve 30 is adapted to be operated by hand, and this is preferably done by means of a cord or other flexible connection 34, which has one of its ends attached to the lever 33 and its other end supported upon the person of the user of the skate within convenient reach. The air-supply ipe 29 is also provided with a valve or cock 35 and leads to one end o an air tank or container 36, which is supported u on the frame 32 in rear of the oil-tank 31 an in front of the rear wheel 2. The tank is supplied with air through a pipe 37, which leads from an airpum 38, mounted upon the front hanger or rac et 6, as shown. This pump 38 may be Upon the oposite end of the shaft 19 is rovided a simi` llies withabevel-V pinion 21 upon a longitudinally-extending` v ,l shaft 22, mounted in suitable hangerszorv 7' The Ashaft 22 has upon its oppoand the minor details of construction may disk 41, secured upon one end of the shaft 26 of the front wheel 2. It will be seen that as the latter is rotated the pum will be actuated to pump air into the tan 36. The engine or motor 3 may be provided with a lubricating device 42 of any suitable form, which is preferably mounted upon the outside of the casing 11, as shown.

In the top of the cylinder of the motor I 1plovide an air cock or valve 43 of any wellown or preferred form. In order to brake the speed of rotation of the wheels in descendin a hill or when it is desired to stop, I provide in the exhaust-pipe 44, Which'leads from the exhaust of the engine to a muflier 45, a valve 46, which is operated by a cord or the like 47, connected to its lever, as shown. The valve 46, which is similar to the valve 30, is normally in its open position, so that when. said cord 47 is drawn u on the valve'will be closed or partially close When this is done the air in the engine-cylinder above the piston will cushion the upward movement of the latter and cause the same to act as a brake for the skate.` If desired, a cushion-pad 48 may be provided on the base 4 of the skate. This pad may be of solid rubber, as shown, or in the form of a pneumatic or hollow aircushion.

From the fore oing description, taken in connection with t e accompanyin drawings, the construction and operation o the invention will be readily understood without requiring a more extended ex lanation.

Various changes in the orm, proportion,

be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what l f-vi.

I claim as new, and desire to secure by Let ters Patent, is-

1. An automobile skate comprising a body hfYiIlg front and rear sup orting-wheels, each provided With a gear-w eel, a longitudinal shaft having gear-Wheels engaging the first-mentioned gear-Wheels, an explosivemotor mounted on the body and having its power-shaft geared to one of the su portin wheels, and an air-tank and a gasolene-tan for sup lying the motor and arranged under the bo ybetween the said supporting-Wheels.

2. The herein-described automobile skate comprising the body having the rear extension, and front and rear supporting-wheels, each provided with a gear-wheel, t e explosive-motor mounted on the rear extension and having the exhaust provided with the valve 46, said valve having the operatingcord 47; the air and gasolene tanks arranged under the body between the supportingwheels, the sup ly-pi e leadin from the gasolene-tank to t 'e car uretero the motor and having the valve 30 provided with the operating-cord 34; the longitudinal shaft having the gears engaging those of the supportingwhee shaft of the motor and the rear su portingwheel, and the air-pump under the ont portion of the skate-body and connected to and o eraited by the shaft of the front supportingw ee In testimony. whereof I have hereunto set my hand in presence of two subscribing Witnesses.
